The embodiments described below by referring to the drawings are exemplary and intended for the purpose of illustrating the present description and are not to be construed as limiting the present description.

Currently electrochemical energy storage power stations are used on a large scale, and energy storage systems, particularly those represented by lithium ion batteries, are growing most rapidly. However, various devices of the energy storage system, particularly the energy storage device, may cause safety problems due to their electrochemical characteristics and external influences. For example, the lithium ion battery can cause safety problems such as explosion and the like due to the electrochemical characteristics of the lithium ion battery and the characteristics of the lithium ion battery which are easily influenced by the outside (factors such as overcharge, high and low temperature, short circuit and the like), and the safety operation of the energy storage system is threatened.

As the size of energy storage power stations increases, the number of devices in an energy storage system also grows linearly, and the magnitude of data (e.g., voltage, current, temperature, etc.) collected for the different devices also expands rapidly. Therefore, how to use a large amount of operation data generated in the operation process of the energy storage system to embody the operation state of the energy storage system so as to conveniently find out the potential safety problem of the operation of the energy storage system is a problem to be solved urgently in energy storage safety and energy storage operation and maintenance.

The embodiment of the specification provides a scene example of an energy storage system running state display method, which is applied to the energy storage system running state display system shown in fig. 1. Referring to fig. 1, the energy storage system operation state display system includes: an energy storage system 102, a server 104, and a client 106. The energy storage system 102 is typically configured with a local controller that is capable of collecting operational data of the energy storage system, such as voltage data, current data, temperature data, and the like. The server 104 is communicatively coupled to a local controller of the energy storage system 102 and to the client 106, respectively. The server 104 may receive real-time operational data of the energy storage system 102 via a local controller and also store historical operational data of the energy storage system 102.

For example, after acquiring the operation data of the plurality of objects in the energy storage system 102 within the specified operation period, the server 104 may analyze the operation data of the plurality of objects within the specified operation period based on the data analysis mode corresponding to the preset operation state analysis mode, and then send the analysis result to the client 106.

The client 106 is provided with an operation state presentation interface corresponding to the operation state analysis mode. The operation state analysis mode is used to characterize a data analysis mode used for analyzing target operation data generated by a target object in the energy storage system 102. The target object is one or more of the plurality of objects. The running state display interface is preset with a threshold interval mark corresponding to the running state analysis mode. Then, the change of the characteristic value of the target object with time in the specified operation period of the energy storage system 102 is displayed in the operation state display interface. Wherein the characteristic value is determined based on the target operation data within the specified operation period, i.e., one of the analysis results described above. The threshold interval identification is used for reminding whether the characteristic value exceeds the threshold interval range.

It should be noted that, the process of analyzing the operation data of the energy storage system 102 by the server 104 may also be directly performed at the client 106. Then, the change condition of the characteristic value of the target object along with time in the appointed operation period of the energy storage system 102 is displayed on the operation state display interface.

Wherein the characteristic value is determined based on the target operation data within the specified operation period; the threshold interval identification is used for reminding whether the characteristic value exceeds the threshold interval range.

In the embodiment of the present disclosure, multiple operation state analysis modes and corresponding operation state display interfaces may be preset for analysis emphasis points of different operation states of the energy storage system. The operation state analysis mode is used for representing a data analysis mode used for analyzing target operation data generated by a target object in the energy storage system.

The hardware architecture of the energy storage system generally includes an energy storage device, a power conversion system, a control system, a thermal management system, auxiliary equipment, and the like. The target object may be any of the above, or may be a more underlying device in the apparatus or system described above. For example, the energy storage device is generally formed by a plurality of battery clusters for storing electric energy, and the target object may be the energy storage device or any battery cluster. Any equipment in the energy storage system may cause a safety problem to the energy storage system, so that the embodiment of the specification can provide a corresponding running state analysis mode and a corresponding running state display interface for any object needing to be subjected to state monitoring in the energy storage system. The operation state display interface is preset with a threshold interval identifier corresponding to an operation analysis mode. The threshold interval identification is used for reminding whether the characteristic value of the target object exceeds the threshold interval range. If the characteristic value of the target object in a certain period exceeds the threshold interval range, the target object can be understood to run abnormally in a certain period.

Specifically, target operational data of a target object of the energy storage system may be obtained within a specified operational period, which may include a real-time operational period and a historical operational period. The target operational data includes, but is not limited to, the following: voltage data, current data, temperature data, electrical quantity data, charge-discharge power data, humidity data, pressure data, vibration data, etc. of the target object may be affected by other environmental parameters. It will be appreciated that the target operational data used by different target objects may be different, the target operational data being determined according to the specific visualization requirements for the target object.

In the embodiment of the present specification, a plurality of operation state analysis modes and operation state presentation interfaces corresponding to each operation state analysis mode are provided in advance. Different target objects can adopt different running state analysis modes to process target running data according to different visual requirements, and the running states of the target objects are displayed through running state display interfaces corresponding to the running state analysis modes.

Specifically, data analysis is performed on target operation data of the target object in a specified operation period based on a data analysis mode of an operation state analysis mode corresponding to the target object, so as to obtain a characteristic value of the target object in the specified operation period. And then, displaying the change condition of the characteristic value of the target object with time in the appointed operation period on the operation state display interface. Because the running state display interface is preset with the threshold interval identifier corresponding to the running state analysis mode, whether the characteristic value of the target object exceeds the threshold interval range in the specified running period can be intuitively observed through the running state display interface. The period in which the characteristic value exceeds the threshold interval range is a period in which the target object operation state is abnormal. Therefore, whether the target object has a safety problem or other abnormal problems can be analyzed through the running state display interface, and the target object in the energy storage system is timely maintained.

In some embodiments of the present description, the target object comprises at least one of an energy storage device, a power conversion system, a control system, a thermal management system, an auxiliary device, a super capacitor, a battery cell, a battery pack, a battery cluster. The target operating data includes at least one of voltage data, current data, and temperature data. The threshold interval range comprises a safety threshold interval in which the characteristic value of the target object is located on the premise of safe operation of the energy storage system. The characteristic value adopts at least one of change rate, mean value, standard deviation, extremum, abnormal frequency, discrete rate and target operation data obtained by data processing analysis based on the target operation data.

The hardware architecture of the energy storage system typically includes energy storage devices, power conversion systems, control systems, thermal management systems, auxiliary devices, and the like. Any device or equipment in the energy storage system is abnormal, which may cause safety problems in the energy storage system. The target object may thus be any of the above, or may be a more underlying device in the apparatus or system described above.

Since the core of the energy storage system is the energy storage device, the energy storage device is used to store energy for subsequent use. The energy storage device may include a plurality of battery clusters, each of which may include a plurality of battery packs, each of which in turn includes a plurality of cells, which are grouped together in series or parallel. The cell is the basic unit in the energy storage system and is a separate electrochemical energy storage device. The cell is typically a single cell having positive, negative, electrolyte, separator, and other components. The cells have specific electrochemical properties and energy storage capabilities. The energy storage device may also be constituted by a supercapacitor. The most likely safety problem is the energy storage device due to the composition and performance of the energy storage system. Accordingly, the embodiments of the present specification will be described with reference to the energy storage device operating state display.

Specifically, the target object may include at least one of a super capacitor, a battery cell, a battery pack, and a battery cluster. The target operating data that can be used to analyze whether the energy storage device is in a safe operating state typically includes at least one of voltage data, current data, temperature data. The characteristic value can be at least one of a change rate, a mean value, a standard deviation, an extreme value, abnormal times, abnormal frequencies, a discrete rate and target operation data obtained by carrying out data processing analysis on the target operation data in a corresponding data analysis mode. Wherein, the discrete rate is also called as variation coefficient, which is obtained by the ratio of standard deviation to average value. Illustratively, taking voltage data as an example, the characteristic value may include at least one of a voltage change rate, a voltage average value, a voltage standard deviation, a voltage extremum, a number of voltage anomalies, a voltage anomaly frequency, a voltage dispersion rate, and voltage data of the target object within the specified operation period. Similarly, if the current data of the target object is acquired, the characteristic value includes at least one of a current change rate, a current average value, a current standard deviation, a current extremum, a current anomaly number, a current anomaly frequency, a current dispersion rate, and current data.

And then, the change condition of the characteristic value along with time can be displayed on a corresponding running state display interface. For example, the change condition of the characteristic value related to the voltage of the battery cell in three historical days with time is displayed on the running state display interface.

In some embodiments of the present description, the specified operating period is divided into at least one target operating condition, the at least one target operating condition including at least one of a charging condition, a resting condition, a discharging condition. Displaying the time-dependent change condition of the characteristic value of the target object in the appointed operation period of the energy storage system in the operation state display interface, wherein the method comprises the following steps: and displaying the working condition identification of at least one target working condition and the characteristic value change curve of the target object in the target working condition along with time in the working condition display interface.

In embodiments of the present description, the designated operating period may be divided by the energy storage operating conditions of the energy storage system. The energy storage system is mainly used for storing electricity and supplying power, so that the operation states of the energy storage system comprise three states of discharging to an electricity load, self-charging and standing. Based on the operating state, the energy storage operating conditions may be divided into a charging condition, a resting condition, and a discharging condition.

The energy storage system must be in at least one of a charging condition, a standing condition and a discharging condition during the specified operation period, and therefore, the specified operation period can be divided into at least one target operation condition according to an operation state of the energy storage system during the specified operation period, wherein the target operation condition comprises at least one of the charging condition, the standing condition and the discharging condition.

In the running state display interface, different target running conditions can be distinguished through the display condition identification, and a change curve of the characteristic value of the target object in the corresponding target running conditions along with time is displayed. For example, different numbers, different letters, different colors, etc. may be used as the condition identifier. For example, charge conditions may be represented by the letter "A", rest conditions may be represented by the letter "B", and discharge conditions may be represented by the letter "C"; the charge condition may also be indicated by the number "1", the rest condition by the number "2", and the discharge condition by the number "3". And in the running state display interface, different running conditions are distinguished by displaying corresponding condition identifiers in the time periods corresponding to different target running conditions.

In some embodiments of the present disclosure, the number of target operating conditions is 2 or more. Displaying a condition identifier of at least one target operating condition, including: and displaying the working condition switching boundary identifiers of the two adjacent target operating conditions at the working condition switching time between the two adjacent target operating conditions. Wherein each of the two adjacent target operating conditions corresponds to an operating period. And displaying the characterization identification of each target operation condition at the time axis corresponding to the operation time period of each target operation condition. Wherein the characterization mark comprises at least one of a character mark, a number mark and a letter mark; the working condition identification comprises a working condition switching demarcation identification and a characterization identification.

Under the condition that the number of the target operation conditions is greater than or equal to 2, different target operation conditions need to be clearly distinguished on the operation state display interface. In the embodiment of the specification, the target operation condition can be distinguished by displaying the condition switching demarcation identifier and the characterization identifier. The working condition switching demarcation mark is positioned at the working condition switching moment between two adjacent target operation working conditions, and the working condition switching demarcation mark can be a straight line, a broken line or other marks with demarcation characteristics. Other indicia with demarcation characteristics may include by color identification or the like. The characterization identifier comprises at least one of a literal identifier, a numerical identifier, and an alphabetic identifier. The text identifier may be an actual operation state of the energy storage system corresponding to the target operation condition, for example, "charge", "discharge", etc.; the digital identifier may be a preset number corresponding to the target operation condition, for example, a number "1" is used to indicate the charging condition, a number "2" is used to indicate the standing condition, and a number "3" is used to indicate the discharging condition; the letter identifier may be a preset letter corresponding to the target operation condition, for example, the letter "a" may be used to indicate the charging condition, the letter "B" may be used to indicate the rest condition, the letter "C" may be used to indicate the discharging condition, the english "charging" may be used to indicate the charging condition, the english "standby" may be used to indicate the rest condition, and the english "discharge" may be used to indicate the discharging condition. It is understood that the characterization identifier may be any preset characterization identifier corresponding to the operating condition.

For example, referring to fig. 3, in the schematic diagram of the coordinate axis shown in fig. 3, the horizontal axis is the time axis, and the time periods t0 to t3 are the designated operation periods. The designated operating period is divided into three target operating conditions, which are: the period from t0 to t1 is a charging condition; the period from t1 to t2 is a standing working condition; and the period from t2 to t3 is a discharging working condition. The vertical axis is a characteristic value axis, and may be at least one of the above-described change rate, average value, standard deviation, extremum, number of anomalies, anomaly frequency, and target operation data. the time t1 is the working condition switching time between the adjacent charging working condition and the static working condition, the time t2 is the working condition switching time between the adjacent static working condition and the discharging working condition, and the time t3 is the switching time between the discharging working condition and other time periods. In order to distinguish different target operation conditions, straight lines are arranged at the time t1, the time t2 and the time t3, character identifiers of 'charging' are displayed in the time period from t0 to t1, character identifiers of 'standing' are displayed in the time period from t1 to t2, and character identifiers of 'discharging' are displayed in the time period from t2 to t 3. The straight lines at the time t1, the time t2 and the time t3 can be replaced by broken lines or other marks with demarcation characteristics.

It is understood that the operating condition switching demarcation identifier is dynamically rendered based on the operating state of the energy storage system within the specified operating period, and there may be only one operating condition demarcation identifier, or there may be multiple operating condition demarcation identifiers. The energy storage operation condition proposed in the embodiments of the present disclosure is a finite enumerated state quantity, and different energy storage systems may be different in name and may be generally divided into: and (5) standing, discharging and charging the operation condition.

In some embodiments of the present description, the threshold interval identification is represented in any one of the following forms: the boundary of the threshold interval range is represented by a solid line or a broken line which tends to be parallel to the time axis; filling the safety display area corresponding to the threshold interval range by adopting a first appointed filling object; and/or filling the unsafe display area outside the safe display area with a second specified filling object. Wherein the first specified padding object is different from the second specified padding object.

In an embodiment of the present description, the threshold interval identification is used to alert whether the characteristic value is outside the threshold interval range. The threshold interval identification may be represented in various ways, for example by a straight line or a dashed line, or by color filling.

In the graphs shown in fig. 4a, 4b, 4c, and 4d, the horizontal axis represents the time axis t, and the time periods t0 to t3 represent the designated operation periods. the period from t0 to t1 is a charging condition; the period from t1 to t2 is a standing working condition; and the period from t2 to t3 is a discharging working condition. The vertical axis is a characteristic value axis v, and may be at least one of the above-described change rate, average value, standard deviation, extremum, number of anomalies, anomaly frequency, dispersion rate, and target operation data.

One form of threshold interval identification may be: two broken lines (v=v1 and v=v2) in the graph of fig. 4a, which are transverse to the time axis and tend to be parallel, represent the boundaries of the threshold interval range, and straight lines may be used instead of broken lines as the boundaries of the threshold interval range. In fig. 4a, the area between the two dotted lines (v 1< v < v 2) is a safe area (or referred to as a normal area, representing a normal operation interval of the target object); the area outside the two dotted lines (v > v2 or v < v 1) is an unsafe area (or referred to as an abnormal area, an alarm area). The curve in the graph represents a characteristic value curve, the characteristic value curve is located in a safety area and can represent normal operation of a target object, if the characteristic value curve exceeds two broken lines, a period corresponding to the exceeding part can be represented as an abnormal operation state of the target object, and the safety problem of the energy storage system can be possibly caused.

Another form of threshold interval identification may be: color filling in the graph of fig. 4 b. Filling a safe display area (v 1< v < v 2) corresponding to the threshold interval range by adopting a first specified object; and/or filling the unsafe display area (v > v2 or v < v 1) outside the safe display area with a second specified filling object. Wherein the first specified padding object is different from the second specified padding object. The first designated object and the second designated object may be different colors. Illustratively, the non-secure display area (v > v2 or v < v 1) may be filled with yellow, and the secure display area (v 1< v < v 2) may be not color filled to differentiate the threshold interval ranges; yellow may be filled into the secure display area (v 1< v < v 2), and the non-secure display area (v > v2 or v < v 1) may be distinguished from the threshold interval range without being color-filled; the threshold interval range may be discriminated by filling the safe display area (v 1< v < v 2) with yellow and filling the unsafe display area (v > v2 or v < v 1) with red. It will be appreciated that yellow, red are merely exemplary colors, and that any other color such as blue, orange, green, etc. may be used. As long as the first specified padding object is different from the second specified padding object.

In some embodiments, if color filling is used for the unsafe display area (v > v2 or v < v 1), the safe display area (v 1< v < v 2) is not color-filled to distinguish the threshold interval range, and the unsafe display area (v > v2 or v < v 1) may be color-filled with a gradient color, and the larger the deviation from the safe display area, the darker the filling color. The severity of abnormal operation of the target object is indicated, and the severity of the security threat of the energy storage system can be indirectly indicated.

In other embodiments, the non-secure display area may be divided more finely, and the non-secure display area may be divided in steps according to the degree of deviation from the secure display area. For example, the non-secure display area may be divided into a hierarchy of alert first area, alert second area, hazard area, and the like. Each area is separated by a dashed line or a straight line or a different fill color is used.

For example, referring to fig. 4c, v=v1 and v=v2 are boundaries of a threshold interval range, v1< v < v2 is a safe display area, and v > v2 or v < v1 is an unsafe display area. In the unsafe display area, the alert first area and the alert second area are divided by a broken line v=v3 and a broken line v=v4. The range of the alarm zone is as follows: v > v2 and v < v4, or v > v3 and v < v1. The alert two zone ranges from v > v4 or v < v3. In order to distinguish the first alarm area and the second alarm area, different colors can be adopted for filling, and the color depth can also be adopted for distinguishing. For example, the security display area is not color filled, the alert first area is filled with light yellow, and the alert second area is filled with dark yellow.

It can be understood that the characteristic value curves can be one or a plurality of characteristic value curves according to the service analysis requirement. For example, two characteristic value curves as shown in fig. 4c may correspond to time-dependent voltage curves of two battery cells, and the two battery cells may be compared in terms of voltage consistency through the two voltage curves. In yet another example, referring to fig. 4d, the characteristic value curve may also include two characteristic values of the same target object, such as a temperature curve and a temperature change rate curve of the a cell. By means of the curve representation of fig. 4d, a deep analysis of the temperature of the same cell can be performed.

Before showing the change condition of the characteristic value of the target object with time in the appointed operation period of the energy storage system, related personnel can select an analysis period in the period selection control of the operation state display interface, and the object selection control selects an analysis object in the energy storage system.

For example, referring to FIG. 5a, the run state presentation interface includes a "period select" control by which the start time of an analysis period may be selected; the system also comprises object selection controls such as an energy storage unit, a Rack number, a Pack number and the like. The energy storage system can be divided into a plurality of energy storage units, wherein each energy storage unit comprises a plurality of battery clusters (batteries) and each battery cluster comprises a plurality of battery packs (batteries). Thus, an analysis object in the energy storage system may be selected by the object selection control. In addition, the running state presentation interface may also include a "site name" control for selecting analysis content of the analysis object, such as voltage, temperature, and the like.

The running state display interface comprises a curve display area and a table display area.

In some embodiments, responsive to clicking on the operating conditions in the tabular display area, a corresponding abnormal frequency graph is popped up. Referring to fig. 5d, the user may perform a clicking operation on the working condition in the table display area, and the running state display interface pops up a corresponding working condition-abnormal frequency graph in response to the clicking operation on the working condition in the table display area.

In some embodiments of the present description, the operating state analysis mode includes temperature consistency analysis. Displaying the time-dependent change condition of the characteristic value of the target object in the appointed operation period of the energy storage system in the operation state display interface, wherein the method comprises the following steps: and displaying a temperature consistency analysis curve and a temperature integrity index curve of the target object in a specified operation period of the energy storage system in an operation state display interface. The temperature consistency analysis curve is used for representing the condition that the temperature mean value of the target object changes along with time; the temperature integrity index curve is used for representing the condition that the temperature of the target object is extremely poor or the temperature standard deviation changes with time.

Wherein the target object is a battery pack or a battery cluster. Since the energy storage devices formed of the battery clusters in the energy storage system are devices having a multi-layered composition structure, it is generally necessary for such devices to perform a lateral uniformity analysis of their lower-level composition devices. Therefore, in order to more clearly understand the operation condition of the energy storage device, the present specification mainly aims at the temperature consistency analysis of the battery pack and the battery cluster.

In some cases, since the battery cluster may include a plurality of battery packs and the battery pack may include a plurality of battery cells, in the embodiments of the present disclosure, in addition to performing operation state analysis on a single object (such as a single battery cell or a single battery pack), temperature consistency analysis may be performed on all objects in the battery pack or the battery cluster, so as to measure stability of a target object and timely find out situations of excessive temperature differences between different constituent pairs in the same target object.

Specifically, the operation state display interface may further include two curve display areas, where one curve display area displays a temperature uniformity analysis curve of the target object in a specified operation period of the energy storage system, and the other curve display area displays a temperature uniformity index curve of the target object in the specified operation period of the energy storage system. The temperature consistency analysis curve is used for representing the condition that the temperature mean value of the target object changes along with time; the temperature integrity index curve is used for representing the condition that the temperature of the target object is extremely poor or the temperature standard deviation changes with time.

For example, referring to fig. 6a, a consistency analysis may be selected for a battery Pack (Pack consistency analysis) or for a battery cluster (Rack consistency analysis). Fig. 6a illustrates, by way of example of a Rack consistency analysis, a temperature consistency analysis curve and a temperature integrity index curve for a target object (energy storage units Es01-RackC 01) over a specified operating period 2022-04-09 14:00:30 to 2022-04-09 16:34:50.

For the battery pack as the target object, the temperature consistency analysis is to determine the time-dependent change of the temperature average value of all the battery cells in the battery pack and the time-dependent change of the temperature range or the temperature standard deviation of all the battery cells.

For the target object being a battery cluster, the temperature consistency analysis is to determine the time-varying condition of the temperature average value of all battery packs in the battery cluster and the time-varying condition of the temperature range or the temperature standard deviation of all battery packs.

In some embodiments of the present description, the operating state analysis mode includes voltage consistency analysis. Displaying the time-dependent change condition of the characteristic value of the target object in the appointed operation period of the energy storage system in the operation state display interface, wherein the method comprises the following steps: and displaying a voltage consistency analysis curve and a voltage integrity index curve of the target object in a specified operation period of the energy storage system in an operation state display interface. The voltage consistency analysis curve is used for representing the condition that the average voltage value of the target object changes along with time; the voltage integrity index curve is used for representing the voltage range or the time-varying condition of the voltage standard deviation of the target object. Wherein the target object is a battery pack or a battery cluster.

Likewise, in order to better understand the operation condition of the energy storage device, the present disclosure may also perform voltage uniformity analysis for the battery pack and the battery cluster. In some cases, since the battery cluster may include a plurality of battery packs and the battery pack may include a plurality of battery cells, in addition to performing operation state analysis on a single object (such as a single battery cell or a single battery pack), in the embodiments of the present disclosure, voltage consistency analysis may be performed on all objects in the battery pack or the battery cluster, and situations such as an excessive voltage difference between different constituent images in the same target object may be found in time.

Specifically, the operation state display interface includes two curve display areas, wherein one curve display area displays a voltage consistency analysis curve of the target object in a specified operation period of the energy storage system, and the other curve display area displays a voltage integrity index curve of the target object in the specified operation period of the energy storage system. The voltage consistency analysis curve is used for representing the condition that the average voltage value of the target object changes along with time; the voltage integrity index curve is used for representing the voltage range or the time-varying condition of the voltage standard deviation of the target object.

For example, referring to fig. 6b, a consistency analysis may be selected for a battery Pack (Pack consistency analysis) or for a battery cluster (Rack consistency analysis). Fig. 6b illustrates, by way of example of a Rack consistency analysis, a voltage consistency analysis curve and a voltage integrity index curve for a target object (energy storage units Es01-Rack c 01) over a specified operating period 2022-06-17:40:22 to 2022-06-17:19:30:22.

Similarly, for the battery pack as the target object, the voltage consistency analysis determines the time-dependent change of the average voltage values of all the battery cells in the battery pack, and the time-dependent change of the voltage range or the standard voltage difference of all the battery cells.

For the target object being a battery cluster, the voltage consistency analysis is to determine the time variation condition of the voltage average value of all battery packs in the battery cluster and the time variation condition of the voltage range or the voltage standard deviation of all battery packs.

It should be noted that, besides the battery pack and the battery cluster, the target object may be other devices or apparatuses that need to perform consistency analysis in the energy storage system.

In some embodiments of the present description, the energy storage system operating state is presented using a secondary interface. The operation state display interface is used as a primary interface; the target object is used as a primary object, and the target object corresponds to a secondary object. The change condition of the characteristic value of the target object with time comprises a characteristic value change curve of the target object. The method for displaying the running state of the energy storage system further comprises the following steps: and responding to the selection operation at any time on the characteristic value change curve, and displaying a secondary interface corresponding to the secondary object. The secondary interface is used for displaying the characteristic value change condition of the secondary object corresponding to the target object at any moment.

Illustratively, the characteristic value of the target object over time includes a cluster-level characteristic value profile of the target battery cluster. The target battery cluster includes at least one battery pack. The running state display method further comprises the following steps: and responding to the selection operation at any time on the cluster-level characteristic value change curve, and displaying the change condition of the package-level characteristic value of each battery package in the target battery cluster at any time. The target battery cluster is used as a primary object, and all battery packs included in the target battery cluster are secondary objects corresponding to the target battery cluster.

For better visual analysis, a secondary interface can be further arranged on the running state display interface. In an exemplary case where the target object is a target battery cluster and the target battery cluster includes at least one battery pack, after the running state display interface (primary interface) displays the cluster-level feature value change curve of the target battery cluster (primary object), the user may click on any time on the cluster-level feature value change curve in the running state display interface to view the pack-level feature value change condition of each or more battery packs (secondary objects) in the target battery cluster at the any time. The running state display interface responds to the selection operation at any moment on the cluster-level characteristic value change curve, and pops up a curve graph as a secondary interface to display the change condition of the package-level characteristic value of each battery package in the target battery cluster at any moment

For example, referring to fig. 7a, the operating state presentation interface presents a cluster-level characteristic value variation curve, i.e., a temperature uniformity analysis curve and a temperature uniformity index curve, for a target battery cluster (energy storage cells Es01-RackC 01) over a specified operating period 2022-08-17:40:22 to 2022-08-17:19:30:22. For the cluster-level characteristic value change curve of the target battery cluster, each time point can be clicked to show the package-level characteristic value change curve of all the battery packages in the target battery cluster. For example, for the second level analysis at time 2022-08-17:17:51:35 in fig. 7a, the run state shows that the interface is responsive to a selection operation on the temperature uniformity analysis curve at time 2022-08-17:51:35, showing the temperature uniformity analysis curve for all of the battery packs in the target battery cluster as shown in fig. 7 b.

It is understood that the primary object may be any device or apparatus or system in an energy storage system that includes a secondary object. For example, the primary object may also be a target battery pack, and the secondary object corresponding to the target battery pack is the battery cell included in the target battery pack. And carrying out secondary analysis on a package-level characteristic value change curve of which the target object is a target battery package, and popping up the secondary interface to display the change condition of the core-level characteristic value of each or a plurality of electric cores in the target battery package at any moment in response to the selection operation at any moment on the package-level characteristic value change curve in the running state display interface (primary interface).

In some embodiments of the present description, the run state analysis mode corresponds to a chart framework template. The generation mode of the change condition of the characteristic value of the target object along with time comprises the following steps: and determining a characteristic value of the target object based on the target operation data in the specified operation period as analysis index data of the target object. Rendering is carried out based on the graph frame template and analysis index data of the target object, and the change condition of the characteristic value of the target object along with time is obtained.

In the embodiment of the present specification, the operation state analysis mode corresponds to a chart frame template. The chart frame templates may include a chart frame template corresponding to a curve display area and a table frame template corresponding to a table display area as shown in fig. 5 b; a graphic frame template corresponding to the graphic display area as shown in fig. 6a and 6b, etc. may also be included.

Before the running state display interface is generated, rendering is needed based on the corresponding chart frame template and the corresponding analysis index data, and a graph and a table needed by the running state display interface are obtained for display.

Specifically, first, data analysis is performed on target operation data in a specified operation period based on a data analysis mode corresponding to an operation state analysis mode to obtain a characteristic value of a target object, and the characteristic value is used as analysis index data of the target object. Rendering is carried out based on the graph frame template and analysis index data of the target object, the change condition of the characteristic value of the target object along with time is obtained, and the characteristic value is displayed in a graph and/or table form on the running state display interface.

Wherein rendering based on the analysis index data of the chart framework template and the target object comprises at least two modes of:

first, the chart frame template and the analysis index data are integrated and then rendered once, and chart rendering data and analysis index data are returned. The method can return all data by only one call, and for a determined visual analysis scheme, the chart frame template and the analysis index data can be processed once only during initialization without loading each time.

And secondly, independently returning the chart framework template and analysis index data, and independently constructing chart rendering and index loading. The chart framework template is only loaded when the chart is initialized or changed, and then only index data is needed to be loaded, so that the chart framework template and the index data are decoupled. But this approach requires the provision of two interfaces to be implemented.
